BACKGROUND Field of the Disclosure

This disclosure relates generally to information handling systems and more particularly to providing power from one portion of an information handling system to another portion of the information handling system.

Description of the Related Art

As the value and use of information continues to increase, individuals and businesses seek additional ways to process and store information. One option available to users is information handling systems. An information handling system generally processes, compiles, stores, and/or communicates information or data for business, personal, or other purposes thereby allowing users to take advantage of the value of the information. Because technology and information handling needs and requirements vary between different users or applications, information handling systems may also vary regarding what information is handled, how the information is handled, how much information is processed, stored, or communicated, and how quickly and efficiently the information may be processed, stored, or communicated. The variations in information handling systems allow for information handling systems to be general or configured for a specific user or specific use such as financial transaction processing, airline reservations, enterprise data storage, or global communications. In addition, information handling systems may include a variety of hardware and software components that may be configured to process, store, and communicate information and may include one or more computer systems, data storage systems, and networking systems.

DETAILED DESCRIPTION

In the following description, details are set forth by way of example to facilitate discussion of the disclosed subject matter. It should be apparent to a person of ordinary skill in the field, however, that the disclosed embodiments are examples and not exhaustive of all possible embodiments.

As used herein, a reference numeral refers to a class or type of entity, and any letter following such reference numeral refers to a specific instance of a particular entity of that class or type. Thus, for example, a hypothetical entity referenced by ‘ 12A’ may refer to a particular instance of a particular class/type, and the reference ‘12’ may refer to a collection of instances belonging to that particular class/type or any one instance of that class/type in general.

In one or more embodiments, power may be provided across a hinge of an information handling system that includes one or more displays. For example, power may be provided across a hinge that couples two displays of the information handling system. In one or more embodiments, input voltage from a power supply to the information handling system may vary. For example, the input voltages may include five volts (5V), twelve volts (12V), and twenty volts (20V), among others. For instance, the input voltages may be direct current (DC). In one or more embodiments, input power may be received by the information handling system via a port included in a chassis of the information handling system. In one example, input power may be received by the information handling system via a first port included in a first chassis of the information handling system. For instance, the first chassis may include a display. In another example, input power may be received by the information handling system via a second port included in a second chassis of the information handling system. For instance, the second chassis may include a second display.

In one or more embodiments, the information handling system may distribute power to its components at one or more voltages. In one example, a backlight driver of a display of the information handling system may utilize a higher voltage than a processor of the information handling system. In another example, the backlight driver may utilize a higher voltage than a voltage provided by an external power supply or provided by an internal power supply. In one or more embodiments, one or more components of the information handling system may dynamically provide power at one or more voltages based at least on one or more voltages provided by an external power supply and/or provided by an internal power supply.

In one or more embodiments, an internal power supply may include a battery. In one or more embodiments, a chassis of the information handling system may include an internal power supply. In one example, the first chassis of the information handling system may include a first power supply. In another example, the second chassis of the information handling system may include a second power supply. In one or more embodiments, the first chassis of the information handling system may include a first portion of components of the information handling system, and the second chassis of the information handling system may include a second portion of components of the information handling system. In one example, power may be transmitted from the first chassis to the second chassis. In a second example, power may be transmitted from the second chassis to the first chassis. In a third example, power may be received by the first chassis from the second chassis. In another example, power may be received by the second chassis from the first chassis.

In one or more embodiments, power at a first voltage, DC, may be increased to a second voltage, DC, before providing the power to a chassis. In one example, providing the power at the second voltage, greater than the first voltage, may reduce power loss in power transmission. For instance, providing the power at the second voltage, greater than the first voltage, may reduce an amount of current to provide the power or to provide an amount of power slightly less than the power. In another example, providing the power at the second voltage, greater than the first voltage, may reduce an amount of conductor material to transmit power. For instance, reducing an amount of conductor material to transmit power may provide one or more environmental benefits. In one or more embodiments, power at the second voltage may be decreased to the first voltage after receiving the power from a chassis. For example, decreasing the power from the second voltage to the first voltage may include increasing a current. For instance, a power value may be a voltage value multiplied a current value.
